Due to an outstanding ratio of strength to weight, carbon fiber reinforced plastics (CFRP) are a promising material for lightweight applications e.g. in aerospace and automotive industry. The main challenge for laser processing is the strong difference between the o...

Continuous carbon fibre reinforced composites (CFRP) are recognized as having a significant lightweight construction potential for a wide variety of industrial applications. However, a today‘s barrier for a comprehensive dissemination of CFRP structures is the lack of economic, quick and reliable manufacture processes, e.g. the cutting and tr...

Composite materials like carbon fibre reinforced plastics (CFRP) or glass fibre reinforced plastics (GFRP) have been in use by the aviation and wind energy industry for years due to their lightweight benefits. With the automotive industry entering the CFRP market, the demand for a more economic CFRP production will in...

Industrial large-volume application of CFRP requires efficient and high-quality processing. Laser processing of carbon fibres is very promising but highly energy consuming due to the large sublimation enthalpy of graphite. In contrast, the sublimation enthalpy of the embedding...

Dissimilar joining of titanium to aluminum is required for several purposes in automotive and aerospace industries. Nevertheless, a number of issues arise due to their different properties, in terms of crystal micro structure, melting point, heat conductivity and coefficient of linear expansion. In addition, brittle intermetallic formation is induced at the interface, thus affecting the...

In this study processing of thin copper C101 (Cu C101) and aluminium 3003 (Al 3003) were investigated, using both infrared (IR), at 1064nm wavelength, and green, at 532nm wavelength, pulsed laser beam sources. The power density (peak power divided by the area of the minimum focused laser beam width) thresholds for ke...

Magnesium is the lightest structural metal; therefore, it has been used in different industries such as automotive, aerospace, electronics and defense. Among different joining processes, laser welding is highly efficient due to its low heat input, high depth-to-width ratio and good mechanical properties. A fiber laser is used to weld AZ31B magnesiu...

Tin phosphor bronze is a tin-based copper alloy which is widely used in the electronics industry. It is being used in components such as computer and mobile connectors, lead frames, vibrating plates and terminals. Because of the high...

For most dissimilar metal combinations, a key challenge which must be addressed for fusion joining processes is the chemical incompatibility of the metals, which typically leads to the formation of brittle intermetallic phases and, consequently, inadequate weld properties. To counteract this issue, a te...
